UNITED CHESTER M. LEFEW, OF HUDDY, KENTUCKY.

RAILWAY-FROG POINT.

Application filed September 12, 1927. Serial No. 219,040.

My invention relates to improvements in railway fro-g points, and the same relates more particularly to a detachable frog point for railways wherein the said point may be reversed in compensating for the wear thereof.

Especially in coal mine tracks serious problems arise concerning the quick wiring of the frog points. The main purpose of this invention is to overcome these problems, and to provide such a switch point which will require considerable less attention than the old type of frog.

An object of my invention is to provide a detachable frog point for railway trackage, which is simple and very efficient for the purpose.

Another object resides in providing such a detachable frog point which may be easily reversed in the event should one of the points thereof become worn.

Whereas my improved frog point is primarily intended for use on mine trackage, the same is equally suitable for use on regu lar steam railways.

Other objects and advantages will become apparent as my invention is better understood from the specification and claim to follow.

In the drawing Figure 1 is a top plan view of a railway frog, showing the frog point with my detachable and reversible point associated therewith and Fig. 2 is a perspective elevation of the diamond-shaped frog point insert.

For a more detailed description of my invention, I now refer to the drawings, in

sert is adapted to be disposed in thesocket formed at the end of the frog rails 2. In this position, the insert is secured in place by suitable screws, or bolts, extending through the holes 7 in attaching relation with the lower portion of the rails 2. The opposite pointed end of the insert is adapted to aline with the side of the frog. rails 2. Ultimately when the insert point is exposed or becomes worn, the screws may be 09 removed and the insert reversed in respect to the socketed end of the frog rails 2. The

insert 4 may be constructed of any material which will'be durable, and willalford the greatest resistance against wear. Having thus described my invention, what I claim as new is V In a wear compensating insert for railway track frog points, wherein the said point is v formed with a V-shaped socket therein, a

diamond-shaped insert adapted for reversible association with respect to the socketed end of the frog point.

In testimony whereof I aflix my signature. I

CHESTER M. LEFEW.
